down with the greatest possible ease, the connection between the bracketand the supporting base or rail being such that the bracket may bereadily detached, removed or replaced or adjusted up and down withoutthe aid of tools or special fittings A further object of the inventionis to provide a: bracket which may be stamped out of sheet metal andeasily bent 'or fashioned by means of dies into final shape, the resultbeing a light, strong and perfectly reliable and safe bracket.

With the above and other objects in view, the nators of which will morefullyappear as the description proceeds, the invention consists in thenovel construe.- tion, combination and arrangement of parts ashereinafter fully described, illustrated and claimed.

In the accompanying drawings, Figure 1 is a perspective view of thebracket. Fig. 1"- is a similar, view of thesupporting base or rail. Fig.2 is a longitudinal section through the bracket and rail, showing theconnection between said parts. Fig. 3 is a rear elevation of a portionof the supporting rail or base. Fig. 4 is a front elevation of the same,showing thebracket in cross-section, the section being taken on the line4-4 of Fig. 2. Fig. 5 is a rear or inner end elevation oi the bracket.Fig. 5 is a horizontal cross-section through the supporting base orrail. Fig. 7 is a perspective view of a bracketol slightly modifiedform, showing also the supporting rail or base. Fig. 8 is a verticallongitudinal section through the bracket and a portion oi the rail. Fig.9 is a rear elevation of the rail show ing the bracket of Figs. 7 and 8associated therewith. Fig. 10 is a from. elevation of the rail showingsaid bracket in cross-section, the section being taken on the line 1010of Fig. 8. Fig. 11 is a detail horizontal section through the inner endportion shown in Figs. 7 and 8.

Like reference numerals designate corresponding parts in all the figuresoi the drawings.

The bracket arm is made out of a single piece of shectmetal oi suitablegage or thickness, which is bent upon a longitudinal line to providewhat may be termed horizontal and vertical flanges l and 2, which aresubstantially :at light angles to each other, the flange 1 forming thefloor or horizontal supporting braceseries of slots 6 in The flanges 1and 2, in the preferred embodiment oi the invention, are substantiallyco eiztensivein length:

and, While the flange or floor 1 is preferably of uniform width from endto end, the flange 2 is made gradually wider as it approaches the rearinner end of the bracket arm, as shown in Figs. 1 and 2 The outer endportionof the flange 2 is rounded off as shown at}, while the extremityof the flange 1' floor 1 is bent upward at right angles to form aretaining lug 5,v which is adapted to be inserted in any one of a orbase 8:

The supporting rail 8 is of channel or double-flanged construction, orin other words, said rail 8 is provided with parallel flanges 9extending backward from its opposite longitudinal edges, as clearlyshown in Figs. 1*- and 6, said flanges being adapted to bear against thewall or other vertical support and to hold the body 10 is turned upwardto form a terminal. stop h1g4. vThe inner end of the fiangeor avertically extending supporting rail of the rail at a suitable distancefrom such wall or sup r port to admit of the insertion and removal ofthe retaining lug 5 of the bracket arm. The rail 8 is provided withholes 11 at suitable points to receive suitable fess teners foranchoring said rail in place against a wall or other vertical support.The slots 6 correspond in shape to the cross-sectional shape of theretaining lug 5, said slots extending transversely of the face of therail.8 and 'being elongated horizontally to conform to the retaining lugand to receive said lug when the bracket arm is tilted upward to aconsiderable angle, said bracket being thereafter lowered or moveddownward to a horizontal position, whereupon the retaining lug 5 engagesbehind the supporting rail and prevents the disengagement ofthe bracketfrom the rail, as shown in Fig. 2.

At its inner end, the flange or brace 2 of the bracket arm is providedwith one or more laterally projecting sustaining lugs 12 which projectat right angles to said flange and are adapted to bear against the outerface of the supporting rail 8. the result being that the bracket arm. issustained'in the position at right rail in the manner clearly shown inFig. 2.

angles to said In some cases it is desirable to make the inner end ofthe flange 2 of considerable Width, and thismay be done either byincreasing the width .of the flange 2 itself and forming the sameintegral with the remainder of the bracket, or the same result may beaccomplished by employing a flange extension or additional piece 13, asshown in Figs. 1 and 2, in which case the .sus- .taining lugs 12 may beformed on said additional piece or extension, or one of said lugs may beformed on the flange 2, while another or othersmay be provided on the 3extension piece 13. In any case, the sustaining lugs 1-2 bear againstthe outer face of the supporting rail 8, I while the retaining lug 5,bears-agsinstthe inner face of pert oi the bracket" while the flange 2constitutes a r the same} The arrangement of the sustaining H Ilugsjust." described, is illustrated in Figs. land ofQThe exte nsionpiece 13 may be riveted to the flange 2, as shown at 14, or securedthereto in any desired manner, the sesuch securing means.

By reference to Figs. 7 to 10, inclusive, it Will be seen that one oithe sustaining lugs 12 may he made of angular construction or providedwith an inwardly extending lip 15 oi the right size to accurately titinto one of the slots 6 ol the supporting rail, the width of said lipbeing approximately equal to the length of the slot 6, so that wheninserted therein, the lower part oi the extended or widened inner end ofthe bracketv base will be prevented trom'swinging ormoving laterally,This is not ordinarily necessary, however, as the shape of theretaininglug 5 will prcventsnch swingingof the bracket by reason of theclose lit between said retaining lug and the slotted supporting rail. ofthis invention to provide the extreme inner vertical edge of the flange2 of the bracket with a small ofi-set lateral extension 16 to projectacross and bear against the corresponding inner vertical edge of theextension piece 13, said arrangement serving to brace the parts 2 and 13relatively to each other and thereby adding to the stability of thebracket as a whole. The extension piece 13 may, as above indicated, beentirely omitted and the width of the flange 2 varied to suit. liy em-It is also within the scope v ploying the extension piece 13, however,bracket arms stones of varying lengths may be used in connectiontherewith Without changing the size, proportions or shape of suchextension-piece. The bracket arm may, of course, be made of any desiredlength, and the general dimensions thereof may be varied withoutdeparting from the principle or sacrificing any of the advantages of theinvention.

Having thus described the invention, I claim:
